Abstract

Owing to high specific strength and stiffness, composites find wide applications in automobile and aerospace industry. In this paper, an attempt has been made to study the vibration characteristics of embedded shape memory alloy wire (SMA). Earlier, experimental modal analysis was carried out on the carbon fiber reinforced epoxy composite beams (CFRP beam) embedded with shape memory alloy wire manufactured by hand lay-up process. Increased levels of pre-strain up to 4% on shape memory alloy wire resulted in maximum increment in natural frequency when activated at 75°C. The experiment also investigates change in modal frequencies in CRPF plates embedded with the SMA wires. The selected pre-strain for experimentation was 4% pre-strain actuated at 75°C.
